# Level 1: Python for Beginners

*Under construction*

Hello and welcome to my Python beginners course. 🐍

In this repository, you will find a variety of **code examples**, **projects**, **exercises**, and **informative insights** in each script.

The goal is to build a **free, high-quality,** and **easy-to-understand tutorial**.

*In the future, I plan to create a detailed script that further deepens the theoretical content.*

---

  - Comparison operators (`==`, `!=`, `>`, `<`, `>=`, `<=`)

  - Logical operators (`and`, `or`, `not`)

- `Loops.py`: Basic introduction into loops

  - `while` loops for conditional execution

  - `for` loops for iterating over sequences

  - Examples including skipping iterations, breaking out of loops, and reverse looping

  - Creating a multiplication table (2d matrix)

- `ErrorHandling.py`: Basics of error handling in Python

  - Using `try`, `except`, `else`, and `finally`

  - Handling `ValueError` and `ZeroDivisionError`

### **03_Functions**

- `Basics.py`: Examples showcasing:

  - Defining a simple function

  - Using parameters to pass values

  - Returning values from functions

  - Getting user input and performing calculations

  - ![Solutions for the tasks](09_Screenshots/03_Basics.png)

- `Args_Kwargs.py`: Making functions more flexible:

  - `funtion(*args)`: use custom amount of arguments

  - `function(**kwargs)`: use custom amount of key:value pairs

### **04_Data_Structures**

- `Collections.py`: Explaination and examples of collection types

  - Lists

  - Sets

  - Tuples

- `Dictionaries.py`: A special type of collection with key-value pairs

  - Adding, updating and removing pairs

  - Accessing pairs

  - Iterating over dictionaries

- `ListComprehensions.py`: Compact way to create and manipulate lists

  - Basic syntax: `[EXPRESSION for ITEM in ITERABLE]`

  - `if` and `if-else` list comprehensions

### **05_Modules**

- `01_BuiltInModules/Math.py`: Exploring Python's `math` module

  - Common mathematical functions like `sqrt()`, `pow()`, `ceil()`, and `floor()`

  - Recreating those functions manually

- `01_BuiltInModules/Random.py`: Exploring Python's `random` module

  - Typically used functions like `randint()`, `shuffle()`, `choices()`, and `randrange()`

- `01_BuiltInModules/DateTime.py`: Python's `datetime` module

  - Getting the current date and time, manipulating dates.

- `01_BuiltInModules/Statistics.py`: Python's `statistics` module

  - Useful statistics funtions like `mean()`, `median()`, `variance()`, etc.

- `02_CustomModules/Supermarket.py`: Creating our own supermarket module!

  - Defining own functions in our module `calculate_total_price()` and `greet_customer()`

  - Using Docstrings 

  - Using `main.py` to import and use those

### **06_OOP_Basics**
